# Hooke’s Law and Modulus of Elasticity
Show/Hide Page Index
### Hooke’s Law
According to Hooke’s law for a small deformation, the stress in a body is proportional to the corresponding strain.” i.e.,
stress ∝ strain
stress = (E) (strain)
Here, E = stress/strain is a constant called modulus of elasticity.

# What is the square root to -300?
Updated: 9/19/2023

You can take the square root of a negative number by using complex numbers and the "i" operator. (-300)^.5 = (-1 * 300)^.5 = (-1)^.5 * 300^.5 = i17.32 because i = (-1)^.5

# Solution for $x^9 + x^6 + x^4 - x^2 + 1=0$
I learned that $5$ and higher order equations can not all be solved. I read the Abel-Ruffini theorem.
My question:
Let $$x^9+x^6+x^4-x^2+1=0$$
This equation can be expressed in the following way:
$$x^9 + x^6 + x^4 - x^2 + 1=(x^4 + x + 1) (x^5 - x + 1)=0$$

$-1/24$
When we add or subtract fractions, we start by making a common denominator (bottom of the fraction). Thus, we multiply 7/12 by 2/2 and 5/8 by 3/3 to obtain: $\frac{14}{24}-$($\frac{15}{24}$)=$-\frac{1}{24}$. | HuggingFaceTB/finemath | |

# 50009. Snake Order
## Problem description
We define a snake-order of a matrix as follows. We first traverse the first row from left to right, then the second row from right to left, and so on. For example, if a matrix has $R = 3$ rows and $C = 2$ columns, then we will traverse (0, 0), (0, 1), (1, 1), (1, 0), (2, 0)... | HuggingFaceTB/finemath | |
